Thymus gland

Vedclass · Answer

(B) The $Thymus$ gland is a lobular structure located between the lungs behind the sternum on the ventral side of the aorta.It plays a major role in the development of the immune system.The $Thymus$ secretes peptide hormones called $Thymosins$,which play a major role in the differentiation of $T$-lymphocytes,which provide cell-mediated immunity.In addition,$Thymosins$ also promote the production of antibodies to provide humoral immunity.As individuals grow older,the $Thymus$ gland undergoes gradual degeneration (atrophy) and is replaced by fat.As a result,the production of $Thymosins$ decreases,leading to a weaker immune response in older individuals,making them more susceptible to infections.

According to the modern theory of aging,our body gradually loses its ability to resist bacteria and pathogens. This process is caused by the gradual disappearance (atrophy) of which organ?
